Making gels
A gel (also known as a lightmap) is produced by assigning a material with a transparency map texture
to a light source. The light’s colored areas are then ltered by this texture and colored in exactly the
same way that a slide projector projects a still picture. For example, the striped-shadow effect of a
Venetian blind can be simulated by assigning a black-and-white striped gel to a light object.
You can assign as many gels as you wish to each light object.
Lights do not use the Texture tags of parent objects.
